Consider that some of these fake accounts could also be used as Honey keys.
They would of course have to work in conjunction with the banks /
sites to utilize this.

It would be rather difficult for a phisher to sort through thousands
of Id's when IP addresses keep getting shut off based on a Honey Key.

You would have to own a lot of BOTs and a lot of patience.
